Abstract
A measuring apparatus for optically measuring a distance to a target object is described. The measuring apparatus has a transmitting device for emitting periodically modulated optical measuring radiation towards the target object, a receiving device for detecting optical measuring radiation which returns from the target object, and an evaluation device for receiving and evaluating detection signals from the receiving device. The measuring apparatus also has a calibration device for calibrating the measuring apparatus, wherein the calibration device is designed to calibrate the measuring apparatus on the basis of detection of uncorrelated radiation which does not correlate with the modulated measuring radiation emitted by the transmitting device. In this case, the uncorrelated radiation may be in the form of background radiation. Alternatively, uncorrelated measuring radiation can be emitted by the transmitting device and can be detected by the receiving device.
